Figure 23. Phylogenetic tree obtained from the Bayesian analysis of the ITS region. The tree is rooted as suggested by the analyses of the COI and 16S genes. Posterior probabilities> 0.75 as well as Bootstrap support values> 50% from the parsimony analysis are indicated at the nodes. Collection sites are given in brackets after the name of the specimens: AK, Alaska; AL, Alabama; CA, California; CN, China; IA, Iowa; IL, Illinois; NL, the Netherlands; SE, Sweden; UK, United Kingdom; green background, North American specimens; pink background, Chinese specimen; white background, European specimens. Vertical lines indicate morphotypes.
